TIRE LINER.

Application filed January 24, 1925. Serial No. e506.

This invention relates to pi'ieiunat'ic tires for vehicles, particularly to attaclnnents or accessories for use in connection therewith, and has for its object the provisicm of a novel liner adapted to be engaged within a tire casing and so constructed and arranged as to protect the inner tube from being punctured from any cause whatsoever.

An important object is the provision of a device of this character which will be simple and inexpensive in manufacture, easy to apply, positive in action, ctlicieut and durable in service, and a general improvement in the art.

\Vith the above and other objects and advantages in view, the invention consists in the details of construction to be hercinalfler more fully described and claimed, and ilh|st-rated in the accompanying; drawings, in which:

Figure 1 a fragmentary elevation oil? a tire and, wheel, a portion of the tire being]; in section to illustrate the device in position,

Figure 2 is a detail view looking at the outside of the liner,

Figure 3 is a cross section on the line 3$:l of Figure Referring more particularly to the drawings, the letter A designates an (n'dinary vehicle wheel. upon which is mounted a pneumatic tube as is customary.

In carrying out the invention we provide a liner for the casing B, which liner is designated broadly-by the numeral 10 and consists of a suitable length of tlexible material such as fabric, leather or the like provided with a series of rivet-like members it which may be of the split type, as indicated in Figure 3 or which may be ol any other preferred type, which rivet members are driven into place through the fabric or other flexible material It) and clinched as indicated. at 12 so as to prevent retraction or Withdrawal. All of these rive s 11 are arranged in substantially contacting relation and it is ol course apparent that there will be small areas between the points oil" contact 0t these rivets, which small. areas we propose to cover by means of other rivets 13 of the same or any preferred type driven in the same or some other manner.

For the purpose of protecting the tube against injury from the clinched ends 12 of the rivets, we provide an auxiliary liner .14 of fabric or other suitable material lonunnher it in. such cover the clinched ehde oil at them Llliiui 2r :lio inner tube. lt l liner i l have i. to
